Water drain
The water drain is a hollow body defining a drainage aperture. The hollow body is adapted for installation in a screen base channel in a lanai, verandah, or screened porch. The hollow body is preferably a flat tube made of plastic, and has a mounting flange around the periphery of one end of the tube. A web or divider wall may bifurcate the hollow body from front to back, adding strength to the walls of the tube. A cap fits over the drainage aperture to limit fluid flow therethrough. The water drain may alternatively be made of aluminum or other corrosion-resistant metal.
This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/014,501, filed Dec. 18, 2007.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to drainage mechanisms, and more particularly a water drain for a lanai, a verandah, a screened porch, or the like.
2. Description of the Related Art
Many homes, particularly in southern climates, are provided with a lanai, verandah, screened porch, or the like. In temperate climates, such partially open structures permit residents and guests to enjoy warm outdoor weather while having a roof for shade and a screen for protection from insects. However, since such structures are at least partially exposed to the elements, it is often necessary to clean the floors with a garden hose or the like, and sometimes standing water will collect after a rainfall. In order to protect the floor from water damage, and for the comfort and safety of the residents and guests, a drainage system to prevent standing water from collecting on the floor and to promote quicker drying is desirable, but preferably in a manner that is unobtrusive and does not mar the aesthetics of the structure.
Thus, a water drain solving the aforementioned problems is desired.
SUMMARY OF THE INVENTIONThe water drain is a hollow body defining a drainage aperture. The hollow body is adapted for installation in a screen base channel in a lanai, verandah, or screened porch. The hollow body is preferably a flat tube made of plastic, and has a mounting flange around the periphery of one end of the tube. A web or divider wall may bifurcate the hollow body from front to back, adding strength to the walls of the tube. A cap fits over the drainage aperture to limit fluid flow therethrough. The water drain may alternatively be made of aluminum or other corrosion-resistant metal.
These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.
Similar reference characters denote corresponding features consistently throughout the attached drawings.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTAs shown in
The water drain includes a flat, tubular body 10 that forms a drain passage adapted for installation through the base channel SB. The tubular body 10 is preferably made of plastic. A suitable material is Kydex® (Kydex is a registered trademark of Kleerdex Company, LLC of Mount Laurel, N.J.), which is a thermoplastic alloy of acrylic plastic and polyvinyl chloride (PVC) that can readily be used for vacuum forming and is very durable, but other plastic materials may be used, if desired. The tubular body may also be made from aluminum or other corrosion-resistant metals or metal alloys, if desired. Representative dimensions of the tubular body 10 are approximately six inches in width, ⅝ inches high, and three inches deep, although these dimensions are only exemplary.
The tubular body 10 may be bifurcated by a web 14 for strength. The web 14 may be a continuous partition wall that extends from front to rear of the tubular body 10, or may be segmented, e.g., in the front, rear, and middle of the tube. The tubular body 10 defines at least one drain passage, or two drain passages 12 when a web bifurcates the tubular body 10. A mounting flange 16 extends peripherally from the front opening of the tubular body 10, defining tabs that extend laterally and have screw location dimples or holes for self-tapping screws or other fasteners used to attach the tubular body 10 to the base channel SB. Preferably, the flange 16 extends circumferentially around at least the top and sides of the front opening defined by tubular body 10, and forms a lip that prevents the tubular body from sliding too far into the installation hole or slot formed through the base channel SB.
A flanged cap 18 may be provided to compression fit over the drain passage(s) 12 to limit fluid flow therethrough, for aesthetic purposes, or to prevent debris from entering and clogging the drain passage(s) 12. The cap 18 may also be made from Kydex, or from PVC or other suitable material. Moreover, the cap 18 may include a plurality of weep holes 20 disposed across the cap 18 in alignment with the drain passages 12. The weep holes 20 permit water to slowly drain through the tubular body 10 when the cap 18 is installed. The cap 18 may be removed when cleaning the lanai, or when heavy rainfall or similar inclement weather is expected.
The base channel SB may be custom manufactured with an appropriate slot to accommodate hollow body screen drain 10, or an installer may cutout the slot with an appropriate tools. For example, the installer may utilize a multi-step process to install the screen drain 10 with, e.g., a 30,000 rpm electric RotoZip with cable drive, a one-eighth inch side cutting bit, a drill with a one-eighth inch bit, a screw driver with a one-quarter inch hex head, and latex caulking. In a first step, the installer finds the lowest areas on floor at outer edge next to the screen S. In a second step, each slot is marked on the base channel SB with a six-inch long by ⅝ inch high template. In a third step, a ⅛ inch pilot hole is made inside and outside of the marked areas. In a fourth step a cut is made through the base channel SB at floor level on both sides, using the RotoZip. In a fifth step, the tubular body 10 is pushed through the cut out from the inside until the mounting flange 16 abuts the base channel 16. In a sixth step, the tubular body 10 is secured with two #6 hex head self-tapping screws on the inside, and latex caulking on the outside, if needed. In a seventh step four ⅛ inch weep holes 20 are drilled in the cap 18, which is then installed on the tubular body 10.
The water drain 10 can be used in areas where standing water after a rain is a problem. Moreover, the water drain 10 can be used to drain water after a floor area has been hosed down for cleaning, thereby saving time and energy.
It is to be understood that the present invention is not limited to the embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
Claims
1. A water drain adapted for installation through a screen base channel in a lanai, verandah, or screened porch, comprising:
- a flat, tubular, elongated body having a front end and an open rear end, the tubular body defining at least one drain passage having a front opening having a height, the tubular body being adapted for extending through a screen base channel;
